How They Filter Air

The first thing to understand is how Nordic Pure and Filtrete filters actually clean the air.

Nordic Air Filter

Nordic Pure air filters use a layered filtration media to trap particles. Most Nordic Pure filters have a sheet of small fiberglass fibers as the first layer to catch larger particles like dust and pet hair. Underneath are layers of increasingly dense synthetic fibers to filter out smaller particles like pollen and smoke. The densest filters can remove particles as small as 0.1 microns.

Filtrete takes a different approach, using an electrostatic filtering media. As air passes through, particles stick to the filter’s electrically charged fibers. Some Filtrete filters also incorporate antimicrobial agents to inhibit bacteria growth. The highest-end Filtrete filters are certified to remove particles as small as 0.1 microns, same as Nordic Pure.

Key Differences Between Nordic Pure And Filtrete

When it comes to outright filtering performance, the top models from both brands are comparable. The key differences come down to filter design and longevity.

  • Filtration Efficiency

One important metric for air filters is filtration efficiency – what percentage of particles of a certain size they remove from the air passing through.

For bacteria-sized particles around 0.3 microns, top Nordic Pure pleated filters are rated to be 90-95% efficient. The equivalent high-end Filtrete filters achieve 85-90% efficiency for 0.3 micron particles.

For even smaller particles around 0.1 microns in size, Nordic Pure fiberglass mesh filters reach 50% efficiency. Comparable electrostatic Filtrete models can reach upwards of 65% efficiency for the smallest particles.

So in terms of raw particle capture percentages, Filtrete filters have a slight performance advantage over Nordic Pure models on the smallest particle sizes. However, both brands deliver high filtration that exceeds industry standards.

  • Filter Media

One advantage of Nordic Pure is that most of its filters use layered fiberglass media. Fiberglass has very consistent filtration properties and stands up well to moisture and humidity. This can help extend the usable lifespan of Nordic Pure filters.

Filtrete’s electrostatic synthetic fibers do not handle moisture quite as well. In humid environments, the electrostatic charge can dissipate faster, reducing the filter’s trapping effectiveness over time. The media itself also eventually breaks down.

If you live in a humid climate or run your AC constantly, the inherent durability of fiberglass makes Nordic Pure filters a better choice in the long run.

  • Filter Designs

Both Nordic Pure and Filtrete offer their filters in a wide range of designs suited for different applications.

Nordic Pure offers basic 1-inch fiberglass filters for furnaces and window ACs. For central air systems and HVAC units, they have 2-to-4-inch thick pleated filters in a variety of efficiencies and frame sizes. Nordic Pure also makes air purifier filters and high-density mesh filters for HVAC systems.

Filtrete has a diverse product line that includes 1-inch and 2-to-4-inch pleated filters, electrostatic air purifier filters, HVAC filters, and high-efficiency filters certified for medical and industrial uses.

No matter what type of filter you need, both brands provide options. Nordic Pure has more fiberglass furnace filter choices, while Filtrete has a edge with electrostatic air purifiers and their elite Maximum filters.

  • Cost Comparison

When comparing Nordic Pure vs Filtrete air filters, cost is often a major factor for consumers.

In general, Nordic Pure pleated filters tend to be 10-25% less expensive than comparable Filtrete models. For example, a 24x24x4 inch Nordic Pure pleated filter with MERV 11 efficiency usually costs $15 to $20. A similar Filtrete 1900 filter averages $25 to $30.

However, Filtrete’s higher-end electrostatic filters like the Elite Allergen models can be 50-100% more expensive than equivalent Nordic Pure filters. For instance, a 20x30x1 inch Nordic Pure elite fiberglass filter runs about $25, while a Filtrete 1900 equivalent is closer to $40.

Across most product tiers, Nordic Pure filters offer significant savings over Filtrete for similar performance. Only at the premium filter levels does Filtrete’s extra power justify the higher prices.

Additional Factors to Consider

Beyond performance and cost, here are a few other considerations when choosing between these top brands:

  • Availability – Nordic Pure filters are carried by major home improvement stores like Home Depot. Filtrete filters have wider distribution across big box and online retailers. Both offer direct shipping.
  • Warranties – Nordic Pure typically provides 1-to-5 year warranties depending on the filter type. Most Filtrete filters come with a 1 year warranty. For the premium models, Filtrete offers a 10 year warranty.
  • Sustainability – Nordic Pure filters generally produce less landfill waste. The metal mesh and fiberglass media are more recyclable than Filtrete’s synthetics. However, both brands offer some eco-friendly filters.
  • Capacity Ratings – Nordic Pure filters list a month rating for filter lifespan. Filtrete rates capacity in terms of air flow, measured in millions of cubic feet. Compare similar models between brands to make sure you get the right capacity.
